The TruClient Ajax – IE protocol recording engine works with the IE9 JS/DOM browser engine (It implies that IE9 is a prerequisite for the TruClient Ajax – IE protocol). Browser engines of lower versions than IE9 (even in compatibility mode) are not supported. That is, applications that were developed with document mode different from the IE9 Standard mode may not work properly with TruClient for IE. In such cases, VuGen injects HTML headers to the application under test (AUT) pages in order that the browser will render them as IE9 Standard mode (document mode). This enforcement is done by default. In the majority of the cases this works. If it does not work contact HP support for assistance to analyze the issue and confirm if there is a workaround.
To verify the AUT Document mode follow these steps:
1. Open IE9 browser outside VuGen and navigate to the AUT web page,
2. Click F12 to bring up the Developers tools,
3. The document mode of the AUT will be displayed as shown below.
